Answer:
10.55% probability
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the CDs are chosen is not important. So we use the combinations formula to solve this question.
1 Bach CD, from a set of 4.
1 Beethoven CD, from a set of 6.
1 Brahms CD, from a set of 3.
1 Handel CD, from a set of 2.
So, D=144
4 CDs from a set of 4+6+3+2 = 15.
So, T= 1365
p= D/T= 144/1365 = 0.1055
10.55% probability that she will choose one by each composer

I know because I googled it
1. y = 2/3x - 5
2. 4x - 6y = 30
Divide 2. by 2
3. 2x - 3y = 15
Substitute 1. into 3.
4. 2x - 3(2/3x - 5) = 15
5. 2x - 2x + 15 = 15
6. 15 = 15
False. There are an infinite number of solutions.
The mean would be 92. Because you add them all up then divide by how many there are

Let's solve your inequality step-by-step.
3 ≤ 7 + g
Step 1:Simplify both sides of the inequality.
3 ≤ g + 7
Step 2: Flip the equation.
g + 7 ≥ 3
Step 3: Subtract 7 from both sides.
g + 7 − 7 ≥ 3 − 7
g ≥ −4
Answer:
g ≥ −4
